Nuclear structure & decays is a research area in nuclear physics that investigates the internal configuration, quantum states, and dynamical behavior of atomic nuclei, along with the mechanisms by which unstable nuclei transform via radioactive decay. It encompasses the development and application of models such as shell, collective, and mean-field theories to describe nucleon distributions, energy levels, and transition probabilities, and studies decay modes including alpha, beta, gamma, and fission processes. The field integrates experimental spectroscopy, reaction studies, and advanced many-body calculations to elucidate nuclear forces, shape coexistence, isomerism, and the evolution of structure far from stability, informing both fundamental theory and applications in astrophysics and nuclear technology.
Incorporated into every aspect of everyday life, the neutron is a fundamental particle of nature. Now, a research collaboration led by Los Alamos National Laboratory has improved the precision of free neutron lifetime measurements. ...
